Can anyone help me. I'm using claymore 11.2 on my RX 570  and only getting 420 h/s for Monero. My card is bios flashed overclocked and with blockchain drivers. I'm getting on the high ends for claymore ETH 29mhs and zcash 312 sols  so I'm confused why it's so insanely low in cryptonote. Also I have tried mining Monero in Minergate software for comparison and im getting 700 h/s  so I feel something is definitely wrong.
